Katy Perry, Lana Del Rey, Little Mix and more gathered at Burton Constable Hall in Hull, England, this weekend for the UK's annual BBC Radio 1's Big Weekend. With the recent bombing in Manchester, security was as tight as possible for the two day music fest. However, the Brits turned it out and showed their love for the year's acts.

Katy Perry, who headlined, sang her new single, "Chained to the Rhythm" as well as her hit, "Roar." But she also dedicated "Part of Me" to Manchester. And despite the sadness surrounding the tragedy, she tried to keep things as up beat as possible.

"I think that you guys are extremely beautiful and I think that we're all extremely brave and we're all in this together, aren't we?" she said. "And you know what? We will still dance, we will still sing, we will still make music. This next one goes out to Manchester and to all the people that know what it means to love music and be a community because of it."

She added, "If you haven't kindly touched the person to our right or left just do that. Just a little connection. Social media can't do that, can it? This is a part of us that they'll never take away from us. Rest in peace, Manchester."

Meanwhile The Chainsmokers brought "Young" to the stage, and Lana Del Rey performed "Lust for Life." Little Mix got the crowd going with their sultry track, "Touch," while Shawn Mendes made the girls swoon with "Treat You Better."
